GANG-PLOW.

nooaeee.

To all whom it may concern:

Be it known that I, PAUL A. VAN SIoKLE, of the city of Brantford, in thecounty of Brant, Province of Ontario, Canada, have invented certain newand useful Improvements' in Gang-Flows, of which the following is aspecification.

This invention relates to a class of gang plow particularly designed foruse with traction engines. usual practice to make each plow adjustablefor depth of furrow by providing it with an adjustable clevis, and alsoby providing means actuated by a set screw for producing a fineadjustment of the angle of the plow to the beam. This adjustment cannotbe made while the plow is under way, and my object is to devise meanswhereby the plows may be adjusted for depth of furrow and pitch almostinstantly and while the plow is in use and without the use of stationaryframes above the gangs.

I attain my object by constructions hereinafter described andillustrated in the accompanying drawing in which- Figure 1 is a sideelevation of a part of a gang plow constructed in accordance with myinvention. Fig. 2 is a plan View of the plow shown in Fig. 1. Fig. 3 isa sectional detail of part of the adjusting mechanism.

In the drawings like letters of reference indicate corresponding partsin the different figures.

In Figs. 1 and 2 I show part of the triangular main frame of the plowwhich is in general of ordinary construction. To the inclined rear bar Oof the main frame the plow beams are connected. For this purposebrackets D are secured to the bar C. Each plow beam E is preferablydouble as shown, and the plow F is secured to the plow beam in themanner I will hereinafter describe.

The forward ends of each plow beam are pivotally connected to a link G,which is pivotally connected with one of the brackets D. To each link Gis rigidly connected a rearwardly extending arm I-I, preferably boltedto the lugs A formed on the link. On each plow beam is secured a notchedquadrant I. A lever J is fulcrumed on the plow beam at K and is adaptedin the usual way to engage the notched quadrant I. A link L is pivotallyconnected to this lever and in Specification of Letters Patent.

Application filed December 27, 1910.

In such plows it is the Patented Nov. 21, 1911. Serial No. 599,323.

the lower end of the link is journaled a-gage wheel M. A pivoted link Nextends from spindle O journaled on the plow beam. On

reference to Figs. 2 and 3 the preferred form of connection will beseen. The end B of the link is bent at right angles, squared and taperedto fit a similarly shaped socket in the rock spindle O. The end of thepart B projects through the socket and is threaded to receive the nut R,which secures the parts together. An arm I is also rigidly secured tothis rock spindle, preferably by being formed integral therewith, and isprovided at its end with a bolt Q sliding in a slot in the end of thearm H. The result of this construction is that if the lever J be raisedthe plow beam E is lowered, as indicated in dotted lines in Fig. 1. Asthe gage wheel remains in contact with the ground, the rock spindle O isrocked and with it the arm P,- which by means of its connection with thearm H, tilts down the link G thus lowering the forward end of the plowbeam, which adjustment is of course equivalent to adjusting the forwardend of the plow beam at the clevis as is the usual practice. It will beseen that by this arr ngement I have devised means for accomplishing thesame effect attained by the adjustment of a clevisand through the mediumof a hand lever which is readily and quickly operated at any time fromthe platform which is usually carried by the main flame.

It will be noted that for adjustment purposes a plurality of holes areprovided in the lever J whereby it may be connected with the link L sothat; the movement of the plow beam for any given movement of the levermay be varied as desired.

A fine adjustment of the inclination of the plow to the plow beam may beobtained in the following manner: The shank of each plow is securedbetween the parts of the plow beam by means of the bolts S. The rearwardbolt passes through a round hole in the plow while the forward boltswork in slots (see Fig. 1). When the bolts are looscried the plow can berocked up and down to a limited extent.

To regulate the adjustment I provide a vertical bolt T passing through abar on the plow beam and through a lug on the plow.

By adjusting this bolt the plow can be adjusted as desired, and thebolts S tightened up to hold everything solid.

To adjust the plow in proper parallelism to the line of draft I dividethe plow beam at one or both sides and secure the parts together by thebolts a working through slots as indicated in Fig. 1. A threaded stem (Zsecured to one part passes through a lug e on the other part and is setup thereto by means of suitable nuts. By adjusting these nuts the plowbeam may be adjusted as desired.

It will be understood of course that the details of construction may beconsiderably departed from while retaining the same principle ofoperation and such variations will fall within the scope of myinvention.

What I claim as my invention is 1. In a gang plow a main frame; a plowbeam; a draft link pivotally connected with the forward end of the plowbeam and the frame; a gage wheel supported from the plow beam behind thelink; and means supported on the plow beam itself and connected withsaid draft link and the gage wheel for vertically adjusting the plowbeam and gage wheel relative to one another and simultaneously rockingthe aforesaid link to similarly adjust the forward end of the plow beam.

2. In a gang plow, a main frame; a plow beam; a vertically movableconnection between the frame and plow beam; a gage wheel supported fromthe plow beam behind the point of engagement between said connection andthe plow beam; and means, supported on the plow beam itself andconnected with said vertically movable connection and the gage wheel,for vertically and simultaneously adjusting the forward end of the plowbeam relative to the frame and the rearward end relative to the gagewheel.

3. In a gang plow a mainframe; a link pivotally connected with theforward end of the plow beam and the frame; an arm connected with saidlink; a gage wheel supported from the plow beam behind the link; andmeans supported on the plow beam itself for vertically adjusting theplow beam Copies of this patent may be obtained for five cents each, by.addressing the Commissioner of Patents,

and gage wheel relative to one another and simultaneously rocking theaforesaid arm to similarly adjust the forward end of the plow beam.

4. In a gang plow a main frame; a link pivotally connected with theforward end. of the plow beam and the frame; an arm connected with saidlink; a rock arm pivoted on the plow beam and having an operativeengagement with the arm of the link; a gage wheel; and means supported.on the plow beam for vertically adjusting the plow'beam and gage wheelrelative to one another and simultaneously rocking the aforesaid rockarm to similarly adjust the forward end of the plow beam.

5. In a gang plow a main frame; a link pivotally connected with theforward end of the plow beam and the frame; an arm connected with saidlink; a rock arm pivoted on the plow beam and having an operativeengagement with the arm of the link; a gage wheel; a link defining thelongitudinal position of the gage wheel and rigidly connected with therock arm; and means for vertically adjusting the plow beam and gagewheel relative to one another.

6. In a gang plow a main frame; a link pivotally connected with theforward end of the plow beam and the frame; an arm connected with saidlink; a rock arm pivoted on the plow beam and having an operativeengagement with the arm of the link; a gage wheel; a link defining thelongitudinal position of the gage wheel and'rigidly connected with therock arm; and means for vertically adjusting the plow beam and gagewheel relative to one another comprising a link at the lower end ofwhich the gage wheel is journaled, and a hand lever fulcrumed on theplow beam to which the upper end of said link is connected.
